>> I have grown Minowase # 3. Definitely a fall radish. Bolts when spring planted. Tolerates frost but not a freeze.
Those look really healthy, Dillard, but I learned my lesson about Daikons. Even when the vendor calls them "mild", I call them "hot". I think they meant "mild for a Daikon". If I use more of my saved seeds, I'll plant in spring and eat the seed pods. Those were very good!
It's interesting to me that they "know" the difference between spring and fall, like Chinese cabbage. Maybe the changing daylength, maybe they can distinguish between "getting longer" and "getting shorter"?
What I bought recently were two that might be like a 'French Breakfast' type, plus a "Giant Butter Radish" sold by Franchi.
Radish 'Flamboyant 3 ' (Franchi, Not spicy. Direct seed in early spring and again in fall. These guys don't care, I guess!)
Dragon Radish (cylindrical, 4-8 inches long, allegedly mild)
Radish Burro Gigante (giant butter)
I might try Watermelon.
